OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.11.1

[-ck]

Hi!

I have a smaller issue I have tested with  2.11, 2.11.2, 3.0 and 3.1 to date. I mine Scrypt coins, namely feathercoin and litecoin.

I have noticed that seemingly random, Cgminer crashes after Stratum disconnect. Usually, the server looses connection and cgminer will restart work after Stratum at pool 0 requests work restart.

Sometimes, after the disconnect, Cgminer crashes completely.


I use a Gigabyte 7970, Windows 8 professional, Ati driver version 8.982-120727a-144338C-Rage 6.

I use the following commands : --shaders 2048 --thread-concurrency 8192 -I 13 -g 2 -w 256

Yes unfortunately the library that does the communications, libcurl, seems to continually be the cause of subtle bugs with stratum. It's ironic that most crashes we've spent a lot of time tracking down are the software bits we didn't write ourselves I've been tempted to rewrite all that part to do it raw, but it would lose the proxy and ipv6 support (though people don't seem to be able to use the ipv6 and the number of proxy users is small).

ipv6 is quite annoying on Windows 8 computers anyway. For some reason, Microsoft managed to implement it in a way that almost always leaks your DNS even when you are behind a VPN.

well, the intensity was set a -1 on the little machine that i am playing with. moving it to 5 raised the hash rate from 6Mhash to 10Mhash. moving it to 6 looked like it  caused the rate to drop a little, so 5 it is.

10Mhash/s? how do you get the Mhash ? ty

Did i mislabel? isn't Mhs, Mega Hashes? I've only been into this for about 2 weeks so it would be easy for me to mispeak.

No, just misunderstood me I think.  I was intending to ask what your mining device was that was getting only 6 to 10Mhs/s.  But you said you were getting a Radeon 6570 which can get you 68 to 100Mhs/s.

Hi guys. Quick question : i'm trying to solo mine CHNcoin and when I run my freshly created solomine.bat, I get error -61. WHat does it mean and how do I er...." decrease TC or increase LG" I don't know what those two settings even mean.

Is it because overclocking software was started at boot or some other process is interfering with CG miner ?

thanks in advance for replying.

Thanks Kano. Your avatar is fascinating, by the way. Is that a picture of you trying to provoke your audience into thinking you are about to sever your forearm with a katana blade ?

Anyhoo.

Turns out I didn't set the MAX ALLOCATION too 100%. That fixed it.

New question : CG miner reports that difficulty is set to 526k. This seems overmuch as the current difficulty of CHNcoin is 8. How do i change this ?

CGMiner reports what the network is saying.  If it says 526k, then it's 526k.  Are you sure you're on the right pool/network?

It's funny you've quoted README's two times now without solving anything, kind of like you're telling me to RTFM while actually you don't really know what you're talking about.

Here's the answer https://bitcointalk.org/index.php?topic=195259.msg2030732#msg2030732

still puzzled by your avatar though

I guess someone could make youtube video reading the FAQ and Readme's to you so you wouldn't have to actually RTFM for yourself.

Reading The Fine (or other term) Manual may be more productive than telling one of the author's of the software "actually you don't really know what you're talking about. ".

Just sayin,

What do I do if cgminer stops responding even when I run it with no tags except --scrypt? I can't get it to make a .bin file so I can see the TC.

Heheh I'm a bit embarresed right now. Sorry. Was just tired and a bit frustrated after trying to configure something that's a little above my skill level. Everything's working fine now though, which is pretty rewarding.

But just in case you didn't get what I meant the first time ...
Explanation of the error message you got and where to find details about tuning scrypt.

Hi,

A number of us are getting CGminer lockups following stratum connection interrupted issues:
https://bitcointalk.org/index.php?topic=188533

The pool never fails over, and cgminer stops hashing and becomes unresponsive to keyboard input.

Any fix or workaround for this issue?

[netvope]

That's like going back to how we mined bitcoins >2 years ago before pools and longpoll. The answer is set the scantime as low as you can before the hashrate drops. If you're solo mining, something like 5s is usual for sha coins. However it can be slow to return results for scrypt so you'll have to experiment.

Thank you for the advice. I have two more questions:

1. I don't see a reduction in the displayed hash rate when I decrease scan-time. Is the displayed hash rate reliable at very low scan-time?

2. Is scan-time=0 a valid setting? According to the README, scan-time is an "Upper bound on time spent scanning current work, in seconds", so it sounds like 0 wouldn't make sense. However, it appears to work, and I found that scan-time=0 allows cgminer to detect new blocks slightly more quickly than scan-time=1. At this moment there are ~5 CNC blocks per minute so every second of stale work counts. I'm solo-mining and I haven't mined a block since I changed to scan-time=0, so I can't tell whether it's truly working.

Hi,

i recently did some solomining and got several hints regarding the expiry setting.

As i tried to understand what the function of this settings are i checked the rm:

--expiry|-E <arg>   Upper bound on how many seconds after getting work we consider a share from it stale (default: 120)

But some questions still remain:

Am i right that a expiry setting of 5 would stop the work on the current block after 5s and switch to the next block?

And why would i want to stop the miner working on a block?

Greetings

I have a question, if someone maybe can answer.  I wouldn't not have thought this a valid question, but have run into it myself.  

--How does "System RAM" connect / associate with "GPU RAM" and "TC" in CGminer?

Example similar to what I ran into;

System mining LTC with 1024mb system ram, with say a TC- 10752
Change
System mining LTC with 512mb system ram, with same TC - 10752  <<<Error -5: Enqueueing kernel onto command queue. (clEnqueu
eNDRangeKernel)

Anyone have thoughts on how / why / what is making the connection with system ram?  Thanks in advance for any help.

3.1.0 - "nogpu" version

Platform:
Win 7 64 bit


After approx. 3-6 hours the following behavior occurs.


1.  Increasingly frequent "Unable to read temperature."  Or something like that.  BFL unit in question still hashing away.

2.  Not long after 1. cgminer stops processing work.  "JSON stratum auth failed (no reason)" messages.  Have to Q out, restart to hash again.


The stratum auth failure message occurs with or without cgminer continuing to process work.  So, pool seems available - just some quirky problem.

You aren't stopping work on a block.
You are stopping work on a work item.

So im trying to build the cgminer-3.1.0-windows and i have been following the directions in the windows-build.txt.
I have done everything up until the step * Build cgminer.exe *.

When i try to run autoreconf -fvi in the MINGW32 prompt it gives me the error autoreconf-2.68: 'configure.ac' or 'configure.in' is required.
Yes i did change the working directory to my cgminer-3.1.0-windows folder.

Im positive that i have done every step correctly.. I will attempt to redo it all just to be sure its not me, but does anyone else know whats going on with this error that prevents me from building this thing already? haha

Please and thank you!
